What is the main function of a capacitor?

Answer 1

They pass AC and block DC. So they are used in filters of various types as well as signal coupling. The capacitor is use to store the electric energy in the automobile ignition system. The capacitor is attached to the secondary winding of ignition coil. When contact breaker breaks the contact to the primary winding and sudden collapse of magnetic flux induces the high voltage to the secondary winding. This excess voltage is stored in capacitor. Capacitor releases the electric energy when it need. It protects cam and contact breaker points from corrosion or rusting.

Answer 2

The capacitor is used to store the charge applied to it.

This stored charge can be used to absorb voltage spikes and voltage drops.

Answer

It's a misconception that a capacitor stores charge. In fact, it stores energy. The net charge on a fully-charged capacitor is the same as on a fully discharged capacitor.

Answer 3

The functionality of the capacitor is storing the electrical energy.it can save and clear the electric charge.current can flow back and froth in a capacitor.In an AC circuit, capacitor reverses its charges as the current alternates and produces a lagging voltage .

Answer 4

A capacitor stores electrical charge. It is similar to a tiny battery. Capacitors are used in electronics for blocking direct currents while allowing alternating current to pass.

Answer 5

To limit spikes in the electrical current and can be applied to both ac and dc applications.

Answer 6

it protects your breaker so you dont over heat and ect. it also prevents you from being un realeaseable due to the normal dc circuit this makes it so you can release.
